# What is Stokes law write its formula?

Stokes law states that the drag force on an object in a fluid is proportional to the velocity of the object relative to the fluid, and is inversely proportional to the viscosity of the fluid. The equation for Stokes law is: F = -6πηrv. where F is the drag force, η is the viscosity, r is the radius of the object, and v is the velocity.

## What is the Stokes law explain?

Stokes law is a expression for the force required to move a sphere through a fluid. It is named after George Stokes.

## What is stock’s force Class 11?

Stocks’ force is the force between two particles in a system that are at rest relative to each other.

## Which of the following formula states the Stokes law?

The Stokes law states that the drag force on an object in a fluid is directly proportional to the velocity of the object, the density of the fluid, the surface area of the object, and the coefficient of drag.

## What is Stokes method physics?

The Stokes method is a means of calculation used to determine the absolute viscosity of a fluid. By measuring the resistance to flow of a fluid (its viscosity), one can determine how easily the fluid flows.

## What is the dimension of Stokes law?

Thedimension of Stokes law is M L T−1.

## When can Stokes law be applied?

Stokes law can be applied to a particle in a fluid when the following conditions are satisfied:

– The particle is small enough that its shape does not affect its drag

– The particle is spherical

– The fluid is viscous

– The particle is moving slowly compared to the fluid

F = μ*v*A

## What is dimensional formula of viscosity?

The SI dimensional formula of viscosity is M L-1T-1.

## What is Stokes law in chemical engineering?

Stokes law in chemical engineering is the law that governs the movement of fluids in a pipe. It states that the closer the fluid is to the walls of the pipe, the slower it will move. This is because the fluid has to overcome the friction between the fluid and the pipe walls.

## What is terminal velocity Class 11?

The terminal velocity of an object is the speed of the object in a fluid environment when the resultant force experienced by the object is equal to zero.

## What is the study of the properties of fluids in motion is called?

The study of fluids in motion is called fluid mechanics.

## How do I apply for Stokes law?

To apply Stokes law, you need to know the Reynolds number, the viscosity of the fluid, and the radius of the object.

## What is Stokes law and how is it used in soil science?

Stokes law is used to calculate the settling velocity of a small particle in a fluid. It is used in soil science to determine the settling velocity of small soil particles in water.

## How does Stokes law calculate time?

Stokes law calculates time by dividing the distance traveled by the object by the speed of the object.

## On what factors does Stokes law depend?

Stokes law depends on the speed at which the object is moving, the density of the fluid, the size of the object, and the viscosity of the fluid.

## How do you find settling velocity using Stokes law?

Settling velocity is the terminal velocity of a particle falling through a liquid. It is given by the following equation:

v = (2 * g * r * s) / (9 * mu)

where g is the acceleration due to gravity, r is the radius of the particle, s is the density of the particle, and mu is the dynamic viscosity of the liquid.
